So far in 2013, Gwen and Gavin have been enjoying downtime together and with their boys after wrapping up a big 2012. Gavin played worldwide tour dates with his band, Bush, during the Summer, and Gwen spent much of the Fall promoting and performing in support of her latest album with No Doubt. The busiest days of Gwen's Push and Shove promotion may be over, but that didn't prevent her from stopping by Jimmy Kimmel Live! with No Doubt in early January, where she performed with the band in one of her signature, midriff-baring looks.
